Explanation:
Slope intercept form is
where m is the slope( average rate of change) and b is the
y intercept( the y value when x is zero).
When x=0, y is 2. This means b=2
Slope is change in y value/ change in x value. Another obvious arbitrary point we are given is (-8,0).
So let use the formula we given.
So our slope is 1/4 so our equation is
1/4x+2
